#About me

A self-taught technology enthusiast from Gliwice, Poland, my foray into programming began at the age of 12. This early start ignited a passion for technology that has grown into a 7-year professional journey, culminating in my current role as a Tech Lead with a deep-seated focus on software architecture, solution design, and pre-sales.

My career path, primarily based at Efigence in Warsaw before transitioning to remote work, has seen me evolve from a Frontend Developer to a leadership position where I spearhead frontend and mobile technology initiatives. This progression is a testament to my deep technical knowledge, adaptability, and commitment to leading teams towards achieving innovative solutions.

My technical repertoire is broad and diverse, encompassing frontend technologies like JavaScript, TypeScript, React, and Angular; backend frameworks such as Node.js and NestJS; and mobile development with Swift, Kotlin, Flutter and React-Native, among others. In addition, my proficiency in DevOps and cloud services, including AWS and Azure, enables me to deliver comprehensive solutions that are scalable, efficient, and aligned with business goals.

I pride myself on my ability to mentor and lead teams with a focus on fostering a culture of innovation, attention to detail, and problem-solving. My approach is characterised by a continuous pursuit of excellence and a belief in the power of technology to transform businesses and lives.
